Hi,
I know that mean centering is not really a remedy for the resultant
multidisciplinary among interaction effect variables. But, it has
become a common practice. I have two questions:
1- In the case of panel data: should we deduct the mean of all the
observations of that particular variables or should we do this by
groups of observation?
2- is there any direct command in Stata for mean centering?
Thanks,
james
